Positek Limited has launched a new pressure transmitter specifically aimed at liquid and gas pressure measurement tasks in submerged equipment. With its protection rating of IP68 sealed to 10 bar/ IP69K, the new S401 series of 35 mm diameter is housed in a 316 stainless-steel construction. The high accuracy piezo resistive sensing element is cupled with the latest ASIC circuitry.

The new pressure transmitter is available with gauge pressure measurement ranges set to customer requirements from 0.6 to 2000 bar and with a wide choice of high level ratiometric voltage, current outputs – some with a low power consumption option for use with battery powered wireless transmitting systems.

The S401 series has a specified range accuracy of less than 0.5 % and a stated non-linearity of less than 0.15 % of range. Repeatability and stability/year both at less than 0.10 % of the measurement range. The transmitter is designed for use in temperatures from -40 to +125 °C (compensated range -20 to +85 °C) with temperature coefficients at less or equal to 0.15 % for both offset and range.

These specifications combine with a fast response time and generous burst and overpressure ratings plus good shock and vibration characteristics to ensure precise and stable pressure measurement over a wide working range with an estimated life of more than 10 million pressure cycles. Installation flexibility is aided by a choice of 1/4″ NPT or G1/4″ threads for the wetted components and electrical interfacing is via a moulded cable to customer’s length requirement with connector/mating connector option.
